I believethis commit (as part ofpython/cpython#23658) was intended to fix issues with the new way in which sphinx handles backslashes in the Python 3.10 documentation.

The issue is that this commit also applied to the 3.8 and 3.9 documentations, which doesn't have this new handling, and so results in escape codes (\n,\t, etc.) being escaped to justn,t, etc.
E.g. theprint documentation hasend='n' instead ofend='\n'.

I'm guessing the files for the 3.8 and 3.9 docs just need to be reverted back to the files from before this commit.

NB: I'm not sure how the source links to different Python version's docs but the issue only applies to 3.8 and 3.9, not for the docs of Python <3.8 or >3.9.

P.S I've not used GitHub much and this is my first time delving into the python docs source so apologies if I've stated/linked anything incorrectly.
